A fire pit has a tub with a hollow interior chamber for receiving ash-producing combustibles. The chamber has a perforated bottom portion. A support is adapted to attach to the tub and be removable therefrom without the use of tools. The support has an ash-collecting compartment disposed directly below the perforated bottom portion when the support is attached to the tub. The support is adapted to support the tub when attached thereto, and to receive hot ashes into the compartment which fall through the perforated bottom portion during combustion of the combustibles, so that the ashes can collect and cool within the compartment and then be transported with the removed support for remote disposal.

The disclosure includes a portable fire pit comprising a housing, a first pair of wheels operatively coupled to a front portion of the housing, a second pair of wheels operatively coupled to a rear portion of the housing, and a fire pit coupled to a top portion of the housing, wherein the fire pit comprises at least one solid vertical wall. In some embodiments, the portable fire pit also includes a cover that converts to a table, as well as a suspension grate to hold firewood and a grill rack to hold food above the fire pit. The grill rack may be configured to be located at different heights above the fire pit, and may also be configured to rotate between positions directly over and to the side of the fire pit.

Apparatus for controlling the flow of air through an air inlet in a solid fuel burner comprises: a mechanical temperature sensor for sensing the temperature within the solid fuel burner, the sensor comprising first and second elongate parts having different coefficients of linear thermal expansion and arranged such that a first end of the first elongate part moves linearly relative to a first end of the second elongate part in response to a change in the sensed temperature; a movable valve member for controlling the flow of air through the air inlet; and a mechanism for coupling the first end of the first elongate part to the movable valve member so as to close or restrict the air inlet as the sensed temperature increases.

A cardboard structure is foldable to form a consumable chimney. The cardboard structure comprises four side wall panels that are connected to each adjacent side wall panel by a longitudinal fold line. The cardboard structure further comprises four floor panels that are each connected to the one of the side wall panels by a lateral fold line. Two locking floor panels secure the floor panels in place to form a floor extending inward from the side wall panels and form a central opening in the floor. The cardboard structure may be formed into an assembled chimney by a few simple folding operations. The cardboard chimney then supports the burning of an accelerant, such as newsprint, which then ignites a solid fuel source, such as charcoal, that is received in the chimney.

Disclosed is an ash clean out mechanism including a burn pot removable from the remainder of the appliance to allow easier cleaning of the auger or other functional components within the appliance. The burn pot can include a handle that a user can pull to remove the burn pot from an adapter collar located within the interior of the appliance. The user can then clean the interior of the appliance and thereafter insert the burn pot into the appliance. For example, the user can push the burn pot by guiding a lower plate of the burn pot along a lip of the appliance and into a landing area where a body of the burn pot can rest on the adapter collar. The burn pot can also form a flow channel around the burn pot body to provide improved airflow during the cooking process.

A fire pit includes a wall panel that cooperates to define a lateral boundary of a burn chamber. The sidewall also defines an upwardly facing opening into the burn chamber. An ash catch is removably received in the fire pit through the upwardly facing opening and may be moved downwardly through the burn chamber to a resting location where the ash catch defines a lower boundary of the burn chamber. The wall panel has an exterior wall segment spaced apart from an interior wall segment to define a passageway there between. The wall panel has a lower opening through which air may flow up into the passageway. The interior wall segment includes a plurality of openings therein through with air may flow out of the passageway into the burn chamber to help fuel a fire in the burn chamber.

The invention relates to auxiliary equipment for reburning combustion products. The technical result is that of accelerating the ignition of fuel and improving fuel combustion in a furnace. A device for reburning combustion products in a furnace is arranged above a combustion unit inside the body of the furnace and is in the form of a hollow body with a bottom inlet hole and a top outlet hole, on the side wall of which hollow body there is formed a horizontal row of evenly distributed air holes. Rectangular protrusions are formed to the right- and left-hand sides of each hole on the inside of the body of the device, said protrusions serving to feed supplementary air, which comes in via the holes, from the outer holes of the furnace into the body of the device, providing for accelerated incineration of residual combustion products without formation of a vortex in the air flows.
